• Check that the service values (VOLTAGE, CURRENT, R(%), X(%)) are according to the
injected quantities and that ROTORANG is close to 0 rad. For this particular injection the
service values are:
•
•
•
•
•
Note that these values identify a point outside the lens characteristic, even if it is close to
the point SE. Neither START nor TRIP is issued.
Execution of the dynamic test
The test may be performed by using two states of a sequence tool that is a basic feature of
test sets.
• State 1: pre-test condition.
Steady voltage and current are applied in order to get a steady high impedance, that is, a
point in the plane R-X which is far away from the lens characteristic. Define the following
three-phase symmetrical quantities (the phase angle is related to phase L1):
